HARMONICA.

SPECIFICATION forming part of Letters Patent No. 505,223, dated September 19, 1893.

Application filed May ll, 1893. Serial No. LP73333. (No model.)

T0 all whom it may concern,.-

Be it known that I, GUSTAVE HYMAN, of New York city, New York, have invented an Improved Harmonica, of which the following is a specification.

This invention relates to a harmonica provided with a slide or lid over the mouth piece, so that the interior of the harmonica may be protected against dust and moisture when not actually in use.

In the accompanying drawings: Figure 1 is a perspective view of my improved harmonica; Fig. 2 a side elevation of the same; Fig. 3 an enlarged cross section of a modification; Fig. 4 a top view of a further modification; Fig. 5 an enlarged cross section of a further modification; Fig. 6 an elevation of Fig. 5.

My improved harmonica is provided with the usual reed plates and mouth piece and may be of suitable size and ornamentation.

To the right and left of the mouth piece a, I form upon the reed plates b, or otherwise, grooves or rails a', which are engaged by the flanged ends c', of a sliding lid or cover c. When this cover is projected over the mouth piece, the latter is entirely concealed and the wind openings are closed, so that neither dust nor moisture can enter thepbody of the harmonica.

In Figs. 1 and 2 the slide c, is shown to be made solid, while in Fig. 4 I have shown it provided with perforations c2, arranged to correspond substantially with the wind openings in the mouth piece. If the slide is fully closed, the solid parts of the slide will cover and protect the wind openings, but when the slide is partly withdrawn and the openings in the parts a, and c, made to register, the instrument may be played upon. Thus in this modification, it is not necessary to detach the slide from the harmonica when the latter is to be used.

In Fig. 3 the grooves or rails are not formed on the reed plates b, but on covering plates d, as shown at d. These covering plates are themselves separately removable, being ini terlocked at their upper ends with the lid c, as describedand entering with their flanged lower ends d2, longitudinal grooves c', in the base plate or body e, of the instrument.

In Figs. 5 and 6 the construction is the same as in Fig. 3, excepting that I employ in addition to the two sliding covering plates d, and sliding lid c, a sliding backf, which is joined to the plates d, in the same manner as the lid. With this construction, any one side or end of the harmonic a may be separately uncovered for inspection and repair.

l. A harmonica provided with a removable lid adapted to be projected over the perforated mouth piece, substantially as specified.

2. The combination of a harmonica having grooves at the sides of the mouth piece, with a anged sliding lid engaging such grooves, substantially as specified.

3. The combination in a kharmonica of a sliding lid over the mouth piece with sliding covering plates over the reed plates that engage the sliding lid, substantially as specified.

4. The combination in a harmonica of a sliding lid and back with sliding covering plates engaging the lid and back, substantially as specified.
